Abstract: An apparatus and method of detecting the presence of a flat tire on a vehicle. A pair of spaced apart pressure sensing assemblies positioned on a roadway are operative to produce a signal corresponding to the pressure applied to one or more pressure sensing elements in each of the pressure sensing assemblies. Comparison of the pressure applied to each of the pressure sensing elements with a value corresponding to a normal non-flat tire indicates the condition of the tires.

Abstract: When a multiaxial robot with a mechanism having spring elements between electric motors of respective axes and robot arms is controlled, the path precision of a tool tip is increased without causing vibrations produced by mechanical interference between axes and high-frequency vibrations of electric motors. A model controller (1) is supplied with position commands X ref_L, X ref_U with respect to the electric motors and outputs model motor position commands .theta.Mm_L, .theta.Mm_U, model motor speed commands ~.Mm_L, ~Mm_U, and model feed-forward commands U FF_L, U FF_U to feedback controllers (10L, 10U) which actuate and control the electric motors and the robot arms. The model controller (1) includes therein corrective quantity calculators (3L, 3U) for calculating corrective quantities (corrective torques) in view of interfering forces acting between the axes from the other axes to cancel the interfering forces. The model controller (1) outputs the model feed-forward commands with the corrective quantities added thereto.

Abstract: A tire tag protector is used to cover a tire tag on the inside of a pneumatic tire during a high-voltage, non-destructive test procedure. The tire tag protector includes a layer of dielectric and is configured to fit completely over the tire tag inside a pneumatic tire. the tire tag protector may also include a layer of conductive material. The tire tag protector is temporarily attached to the tire by an adhesive or by prongs that engage the tire tag. The tire tag protector prevents the high- voltage electrode used in the test procedure from snagging on the tire tag and prevents the sensitive electronic equipment of the tire tag from being damaged by the high- voltage test environment.

Abstract: A channelizing oscillator (10, 110, 130, 150) includes a phase-locking oscillator (12) whose output frequency is channelized in a conventional manner by a dual-modulus divider (18), and both a modulus controller (38) and counters associated with A and N inputs of an integrated chip (20). Secondary channelizers (46, 112, and 154) are provided that channelize the output frequency in smaller frequency increments than those provided by the phase-locking oscillator (12). By channelizing in two places by two different sizes of frequency increments, a bandwidth can be channelized in smaller frequency increments. By mixing the channelized frequencies in quadrature, channelized frequencies are produced in which periods of the new wave are essentially constant, filtration requirements are minimized, the compare rate is maximized, and the phase-locking speed is maximized. In preferred embodiments, the quadrature mixers (58 and 142) include means (96) for selective amplitude matching of in-phase and quadrature-phase components. In various embodiments, the secondary channelizers (46, 112, and 154) include a secondary phase-locking oscillator (48) that is channelized, or a direct digital synthesizer (114) and D/A converters (116A and 116B), cascaded binary-rate multipliers (160A, 160B,'and 160N), or cascaded digital-rate multipliers (160A, 160B, and 160N).

Abstract: A method of measuring motion of an object by magnetic resonance imaging including applying a pulse sequence to spatially modulate a region of interest of said object. At least one spectral peak is acquired from the Fourier domain of the spatially modulated object. The inverse Fourier transform information of the acquired spectral peaks is computed. The angle images are computed from the spectral peak. The angle images employed to measure motion of the object. The method may employ a SPAMM pulse sequence as the pulse sequence. The angle images may be employed to compute directly and automatically, planar strain in two dimensions or a full strain tensor in three dimensions. The data may be useful in detection and quantification of myocardial ischemia and infarction. The angle images may also be employed to generate data equivalent to planar tag data automatically and can be employed to generate any desired tag separations. The angle images may also be employed to compute displacement, synthesize tag patterns and compute optical flow without requiring the use of regularization.

Abstract: The temperature and flow rate of steam introduced to a gas turbine and a combustor is controlled properly through mixing intermediate-pressure steam and high-pressure steam. Thus, two different requirements; i.e., adjustment of steam temperature and securing of a sufficient steam flow rate, can be satisfied simultaneously. As a result, it becomes possible to simultaneously achieve control of the clearance of the blade ring of the gas turbine by means of steam and cooling of the combustor by means of steam.

Abstract: A personal flotation device (PFD) with flotation foam is disclosed. A soft PFD, or a life jacket, is made up of a number of individual pockets in which flotation foam is enclosed to provide buoyancy. An additional layer of soft foam is fastened between the flotation foam and the material forming one side of each individual pocket to create a rounded edge that covers the harder edges of the flotation foam that cause user discomfort. To manufacture the soft PFD, two layers of material are first fastened to each other at their edges to form at least one open pocket. A soft foam layer is fastened by its edges to the exterior of one or both of the material layers, or simultaneously as the two material layers are fastened together. The open pocket is subsequently turned inside out to form an inverted pocket. This causes the material layer with the fastened soft foam layer to round out. Flotation foam is then inserted into the inverted pocket, which is subsequently closed.
